' Specification of Letters ream. Patented Nov. 2, 1915..

Application filed December 29, 1914; Serial No. 879,522.

To all whom it may concern:

Be it known that I, EDGAR W. SMITH, a citizen of the United States,residing at Winnemucca, in the county of Hunrboldt and State of Nevada,have invented new and useful Improvements in Brakes, of which thefollowing is a specification.

The invention relates to'brakes, and more particularly to the class ofvehicle or car brakes.

The primary object of the invention is the provision of a brake whereinminimum leverage will be required for the application thereof, and also.the employment of the .usual brake beams is entirely dispensed with. v

Another object of the invention is the provision of a brakeof thischaracter wherein the brake shoes are carried by bands which partlyencircle the brake wheels, the

latter being integrally formed with the wheels of the car orv Vehicle sothat each wheel will be braked, and the said brakes can be quickly andeasily applied with the requirement of minimum enertion.

A further object of the invention isthe provision of a brake of thischaracter wherein the construction thereof is of novel form, possessingsimplicity, durability, reliability and efiiciency in its operation, andalso one which may be manufactured at a minimum cost.

With these and other objects in view, the

invention consists in the construction, combination and arrangement ofparts as will be hereinafter fully described, illustrated in theaccompanying drawings, an] pointed out in the claim hereunto appends Inthe drawings: Figure l is a side elevation of a car truck, showing thebrake constructed in accordance with the inven- Fig. 2 is a top planView 4 is a vertical longitudinal sectional view through the truck.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, A

designates a truck frame with its bolster 13,.

axles C, and traction wheels D, the same being of the ordinarywell-known construction, and has mounted thereon the brake hereinafterfully described.

integrally formed at the inner side of each traction wheel 1) is anannular brake flange or drum 10 on'which'act the brake comprising a pairof brackets 11 which are fixed'transversely in spaced relation to eachother to the under side of the bolster B,

and to which are connected the brake bands 12, the same being trainedover the flanges or drums 10, and one an of these bands are connected bymeans of pivots 13 with rocking levers 14, while the other pair of bandsare connected by means of pivots 15 to a pair of levers 16, the levers14c being pivoted at 17 in hangers or bearings 18 fixed in the topsection of the bolster 13, while connected by means of pivots 19 tothelevers 16 are links 20, the latter being also pivoted at 21 to a fork 22which is pivotally con nected to an operating rod or cable 23 controlledfrom any suitable brake standard mounted upon the body of the car at oneend thereof. as

The pairs of'rocking levers 14 and 16 have pivotally'connected mediallythereof coupling rods 24 so that on the tightening of the rod or cable23 the levers 14 and 16 will be shifted for the tightening of the bands11 about the flanges or drums 10 for i the braking of the. wheels I) ofthe vehicle or car. To release the brake it is only neces; sary toslacken the rod or cable 23 so that the wheels D will be free.

Mouxited; on the bands 11 are brake shoes 25 which are adapted tocontact with the flanges or drums 10 on the car wheel 1) when the brakeis applied so as to frictionally hold the flanges or drums for thestopping of the car or vehicle. The shoes 25 can be readily detachedfrom the band in event, of wear thereof so that new shoes can be placedin their stead. The brake shoes 25 are detachably connected to the bandsv11 through the medium of keys or pins 26 which are passed through eyes27 integrally formed with the ings, it is thought that the constructionand manner of operation of the device will be clearly understood, andtherefore a more 7 extended explanation has been omitted.

cross brackets fixed to the bolster of the I truck in spaced parallelrelation to each other, hangers fixedto'the bolster betweenthe saidbrackets, levers pivoted tosii'id hangers,- brake bands encircling thebrake drum and hgtving the ends of thelr lowermost stretches pivoted tothe brackets, adjustable coupling rods pivoted to the leversintermediate the ends thereof, levers pivoted to the said levers, anoperating fork, and links pivoted to the last-named levers and the saidfork.

In testimony whereof I aflix my signature in presence of two witnesses;

I EDGARW. SMITH. Witnesses:
